Thread: Rebuild time

We had similar happen to our old farm truck and it made a hell of a racket when it dropped the hot plug. It did it twice over it life time but never with as much damage and distortion as that. Time to take it to the machine shop and have them work their magic. Best of luck with it would love to see some pics of the piston and rings

Well; the only thing you can do now, is strip the engine completely, clean all of the parts thoroughly and measure and inspect them.

If you don't have micrometers you will save some money anyway by doing the cleaning and disassembly. If you can measure the crank and bores yourself, you will be able to assess whether it is cheaper to keep that block and have it machined, or look for a better one.

Money can also be saved sometimes, by sourcing good quality parts and if your engine re-conditioner is a Capricorn buyer, he can get them cheaper than you can.

For a full engine rebuild - not including ancillaries - budget for $2500 to $3000,

Thanks for the replies guys. I will continue to strip it down and see what else i find. I was hoping to keep this all original so hopefully the bock can be saved.

What are peoples thoughts on this for a replacement?

The more i think about the old engine the more i am leaning towards getting something with more performance.

It will mean that it will no longer be original however i can always revert back one day if i wanted to as the 200 tdi is a direct swap as i understand?

Photo looks to be a 300tdi

Firstly, whilst the engine will fit into the Land Rover if it is a 200tdi, it is not a simple operation and requires some fitting skill to make it fit the gearbox. In addition, the 200tdi exhaust manifold from a Discovery fouls the chassis but the 300tdi manifold will fit. The Defender 200tdi manifold apparently fits, but is no longer available new.

Also, think about the ancillaries such as the intercooler and viscous coupling fan, which will not fit easily and require modifications to the front panel.

Secondly, while the engine is much more powerful, the gearbox can't hack it and the mainshaft will flex badly if revved high in 2nd, or 3rd gear. Really a stronger box needs to be fitted.

Thirdly, if you buy the engine, make sure that you can see and hear it running first.

I am approaching the end of a 200tdi conversion on my S3 LWB, so if you would like a copy of what I have written so far, send me a PM,

Cheers Charlie

PS If you do a conversion, get permission from the licencing authority before you start.

Thanks chazza for the good advice. I really just need to get the old block to a machine shop for diagnosis then go from there

Hi Ben, do u realise that the 2.25 diesel engine block, crank and camshaft is the same as a petrol engine block? The only difference in the bottom end is the pistons, if its a 3 bearing crank that is. Obviously the head is different. If ur block is no good just get a petrol block, and if it needs it, bore it out and fit diesel pistons, as ive been told. I was told to go the other way actually, but i really wanted a diesel for my s2a and now ive got one. I was thinking about putting 200tdi manifolds of a defender on my diesel to get a bit more power. My s2a g/box is plenty strong enough for the 200 or 300tdi conversion. Unfortunatly the s3 g/boxes were not as strong. Good luck with it Ben.

Cheers Rod
